Meluhan king, Daksha, sends his emissaries to Tibet, to invite the local tribes to Meluha. Shiva, chief of the Guna tribe, accepts the proposal and moves to Meluha with his people. Once reached they are received by Ayurvati, the Chief of Medicine of the Meluhans. The Gunas are impressed with the Meluhan way of life. On their first night of stay the tribe wake up with high fever and sweating. The Meluhan doctors administer medicine.
